• Spectral and time-frequency domains features for quantitative lower-limb rehabilitation monitoring via wearable inertial sensors 

  Tedesco, Salvatore; Urru, Andrea; O'Flynn, Brendan (Institute of Electrical and Electronics Engineers (IEEE), 2018-03-29)

  Inertial data represent a rich source of clinically relevant information which can provide details on motor assessment in subjects involved in a rehabilitation process. Thus, a number of metrics in the spectral and ...
• Intensity-modulation direct-detection OCDM system based on digital up-conversion 

  Ouyang, Xing; Antony, Cleitus; Zhao, Jian; Talli, Giuseppe; Townsend, Paul D. (Optical Society of America, 2018)

  We propose for the first time an orthogonal chirp-division multiplexed (OCDM) IM/DD system based on digital up-conversion for access network applications. It exhibits better resilience to impairments such as chromatic-di ...
• An MMI-based tunable laser for integrated photonic circuits 

  Caro, Ludovic; Dernaika, Mohamad; Peters, Frank H. (Optical Society of America, 2018-05)

  A single mode, tunable semiconductor laser is presented for the L band. This facetless, regrowth-free laser shows a tuning range extending from 1564nm to 1611nm, with side-mode suppression ratio values over 30dB.
• On-chip optical interconnect on silicon by transfer printing 

  Liu, Lei; Loi, Ruggero; Roycroft, Brendan; O'Callaghan, James; Justice, John; Trindade, Antonio Jose; Kelleher, Steven; Gocalinska, Agnieszka; Thomas, Kevin; Pelucchi, Emanuele; Bower, Christopher A.; Corbett, Brian (Optical Society of America, 2018)

  On-chip optical interconnects consisting of transfer-printed micro-LEDs and photodiodes are presented. Static and dynamic data transmission and bi-directional interconnect are demonstrated. The results show the potential ...
• Point tracking with lensless smart sensors 

  Abraham, Lizy; Urru, Andrea; Wilk, Mariusz P.; Tedesco, Salvatore; Walsh, Michael; O'Flynn, Brendan (IEEE, 2017-11)

  This paper presents the applicability of a novel Lensless Smart Sensor (LSS) developed by Rambus, Inc. in 3D positioning and tracking. The unique diffraction pattern attached to the sensor enables more precise position ...
